(a) Stereo cartoon representation of the α-carbon B-factors alignment for XacFPR (green), AvFPR (pink), PaFPR (blue) and RcFPR (yellow) by Pymol. Positions with larger fluctuations are indicated in wide cartoon while those with the lower fluctuations are shown as thin cartoon. FAD from XacFPR is displayed in space filling with carbons in green. Inset; detail of C-terminal homologous residues of FPRs from subclass IA in sticks. Interactions between Glu258 and FAD in XacFPR are shown as dashed lines. The FAD and the side-chain of Glu258 are in space filling and sticks, respectively, and both CPK coloured. (b) Detail of the different exposition of FAD in XacFPR (blue) and RcFPR (dark yellow) due to the conformation of side chains of Lys259 and Glu270, respectively. Red balls represent water molecules and respective polar contacts of Lys259 and Glu270 with their environment are shown in dashed lines.
